Pitch Marks at Peaks or Valleys?
This paper deals with the problem of speech waveform polarity. As the polarity of speech waveform can influence the performance of pitch marking algorithms (see Sec. 4), a simple method for the speech signal polarity determination is presented in the paper. We call this problem peak/valley decision making, i.e. making of decision whether pitch marks should be placed at peaks (local maxima) or a...
متن کاملCounting Peaks and Valleys in a Partition of a Set
A partition π of the set [n] = {1, 2, . . . , n} is a collection {B1, B2, . . . , Bk} of nonempty disjoint subsets of [n] (called blocks) whose union equals [n]. In this paper, we find an explicit formula for the generating function for the number of partitions of [n] with exactly k blocks according to the number of peaks (valleys) in terms of Chebyshev polynomials of the second kind. Furthermo...
متن کاملC. C. Tan: a life of peaks and valleys.
I first met C. C. Tan (Tan Jiazhen) in 1946 at the of the spots if they do occur. The penetrance and size of spots are greater at lower developmental temperatures. University of Texas in Austin where I was visiting at the time. He was there to give a seminar on “mosaic The other 11 alleles produce a much larger amount of black pigment, which may cover almost all the elytron, dominance” in ladyb...
متن کاملComparative LC-MS: a landscape of peaks and valleys.
Quantitative proteomics approaches using stable isotopes are well-known and used in many labs nowadays. More recently, high resolution quantitative approaches are reported that rely on LC-MS quantitation of peptide concentrations by comparing peak intensities between multiple runs obtained by continuous detection in MS mode. Characteristic of these comparative LC-MS procedures is that they do n...
متن کاملCounting peaks and valleys in k-colored Motzkin paths
This paper deals with the enumeration of k-colored Motzkin paths with a fixed number of (left and right) peaks and valleys. Further enumeration results are obtained when peaks and valleys are counted at low and high level. Many well-known results for Dyck paths are obtained as special cases.
